Novel anti-settling and anti-inclining underground comprehensive pipe rack structure in soft soil foundation and construction method of novel anti-settling and anti-inclining underground comprehensive pipe rack structure

Abstract

The invention discloses a novel anti-settling and anti-inclining underground comprehensive pipe rack structure in a soft soil foundation. The novel anti-settling and anti-inclining underground comprehensive pipe rack structure comprises a comprehensive pipe rack arranged in a strip-shaped foundation pit, wherein Larsen steel sheet piles are arranged on the two sides of the strip-shaped foundationpit so as to support soil bodies on the two sides; the comprehensive pipe rack is arranged on a concrete cushion layer, and the concrete cushion layer is arranged on square root pile supporting seatsformed by pouring concrete; at least three oblique auxiliary piles are obliquely arranged on each of the front portion, the rear portion, the left portion and the right portion of each of root pile main piles correspondingly, and reinforcing steel bars are arranged in the root pile main piles and the oblique auxiliary piles; oblique pile holes are obliquely formed in the Larsen steel sheet piles,and oblique pile bodies are obliquely downwards arranged at the oblique pile holes; and the comprehensive pipe rack is formed by connecting a plurality of sections of branch pipe racks, two rows of oblique pile bodies are arranged on the left side and the right side of each section of branch pipe rack correspondingly, two oblique pile bodies are arranged in each row, and outward concrete extendingblocks are arranged on the side walls of the oblique pile bodies. The invention further provides a construction method of the structure. The structure and the method can effectively prevent the comprehensive pipe rack in the soft soil foundation from settling and inclining.

Description

technical field [0001] The invention relates to a new method for strengthening and stabilizing an underground comprehensive pipe gallery in soft soil foundations, which is suitable for the design and construction of comprehensive pipe galleries under road pavement in different soft soil foundations, and belongs to the field of underground pipeline engineering, especially for soft ground and anti-inclination soft tunnels. A new structure of underground comprehensive pipe gallery in the ground foundation. The present invention also relates to the construction method of the novel structure of the underground comprehensive utility gallery in the anti-subsidence and inclined soft soil foundation. Background technique [0002] In recent years, with the development of urban construction in our country, the construction scale of underground comprehensive utility corridors is also expanding. The underground comprehensive pipe gallery greatly facilitates the maintenance and repair of...

Problems solved by technology

[0003] However, due to the limited friction between the traditional piles and the soil, the traditional method of preventing the settlement and inclination of the underground comprehensive pipe gallery leads to more or less uneven settlement of the comprehensive pipe gallery, especially for the pipe gallery without piles at the bottom. The subsidence is more obvious
